Threadless to Threaded?

Thanks, Mish

Mish: Very few shops have appropriate tooling for installing virgin threads on a fork that
originally had none. Most of the dies that shops use are fine for cleaning threads up, or adding new
ones providing the guide threads are original (in other words, once a die is cutting entirely new
territory, having left behind the original threads that it could use as a guide, thread quality
declines dramatically). The best way to cut threads is on a lathe, but not too many people are set
up for that.

Of course, aluminum threads might cut like butter, but I'm not aware of anybody using threaded 1"
aluminum steer tubes, as I don't think they'd be very strong (the threads would be very easily
damaged with use).

There are many benefits to using a threadless system; is there some particular requirement for your
project that requires a threaded fork?

Replace the fork?

Easy, replace the fork

gmisher-<< Can a fork with a 1" steel or alloy threadless steerer be converted to a threaded

If steel, the steerer can be threaded...but must be done in such a way to ensure the threads are
parallel to the fork crown seat, like on a lathe. We charge about $50...

Not for aluminum, can be threaded but material too soft for this.

Mike,

Not *required*, no. What I was thinking of doing was replacing a cro-moly fork on my hybrid with a
Winwood (or similar) carbon fork with metal steerer, but preserve the threaded headset and use a
suspension stem. I have a machine shop nearby that has done some odd things for me before that could
probably thread the steerer for me. BUT if strength of threaded alloy steerer is going to be a
problem, then that's not going to work anyway. I can go threadless and give up the suspension stem
if needed. Or, I can just keep the fork I have for that matter.

FYI - My project is this: I have an approx 7 yr old Trek 750 that I'm trying to build up into a more
suitable bike for unpaved roads/cinder trails in Europe and eventually Alaska rides. I'm thinking of
upgrading to XT 9 speed drivetrain, good 36 spoke touring rims/hubs, and some type of mild front
suspension (hence the threaded fork/suspension stem described above).

Originally I was looking for a simple 700c suspension fork that would accept canti brakes, but that
became enough of a hassle that I thought of going the route described above. I know everyone is
using V brakes now, but the bike came with canti's, has non linear levers, has no cable stop for V
brakes on top tube, and linear brakes interferer with my rear rack.

Thanks - as always - for your input.

No need to give up the suspension stem. i" threadless Softride stems are still easly available in
both steel and aluminum, in several lengths.

Do not assume that the inside diameter of all threadless steerers will be appropriate for use with a
quill stem. Freed from the constraints of having threads cut in it, a manufacturer might specify a
steerer tube that will have walls thinner (or thicker, which would almost certainly the case with
aluminum) than one that will provide a proper match for a Ø 22.2 stem quill.
